DS1836AS-5+T&R

Supervisors Overview

The DS1836AS-5+T&R is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, belonging to the MicroManager series. It functions as a voltage monitor with a single monitored input and features a push-pull/totem pole output type. The device provides an active low reset signal with a minimum reset timeout of 200ms. It operates within a temperature range of -40°C to +85°C and utilizes an 8-SOIC package. The component is currently marked as discontinued.

Supervisors Feature Summary

• Integrated backup battery circuit functionality for maintaining system state during power transitions
• Provides manual reset capability via external pushbutton interface
• Delivers active low reset output using push-pull topology

Supervisors Applications

• Voltage sequencing in embedded systems requiring supervised power rails
• Backup battery monitoring applications where power failure detection is critical
• Microprocessor reset generation in industrial control environments

Supervisors Procurement Notes

This component is officially listed as discontinued by the manufacturer. Availability is restricted, and sourcing may require checking for limited stock or factory special orders through authorized distributors. Verify end-of-life status and lead times carefully before finalizing design-in decisions due to potential supply constraints.

Supervisors Selection Notes

Select this part only if legacy compatibility with the MicroManager series is required. Consider the 8-SOIC package constraints and the specific 4.37V threshold voltage. Evaluate alternative modern supervisory ICs from the same manufacturer that offer similar push-pull outputs and backup battery features but are currently in production.

Supervisors Part Context

The DS1836AS-5+T&R belongs to the Maxim Integrated MicroManager family of supervisory circuits. This series is designed to provide reliable power management solutions for microprocessor-based systems. The AS variant typically denotes specific performance characteristics within the broader DS1836 product line, focusing on robust voltage supervision and battery backup integration.

Supervisors Replacement Considerations
